The Legend of Zelda: The Wind Waker - Magtail

The Magtail is a centipede-like enemy that is resistant to lava, as one of the locations it can be found is in Dragon Roost Cavern. When Link gets close, they will attempt to bite him. Once it is struck by an attack, they curl up into a ball, where it can be picked up and moved, as well as placed on a switch if needed. When they come out of the ball, they will have recovered all of their health. They can be killed in one hit by parrying, although the Skull Hammer is a useful weapon when they are curled up.
